SEAT ATTACHMENT FoRwATER-c osETs.

sPEcIEIcA'rIoN forming part of Eater Patent No. 534,018, dated February 12, 1895.

I -Application filed December 15, 1894- Serial No. 581.897. (No model.)

To all whom it may concern.-

Be it known that I, JOHN H. STEVENS, J r., of Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain new and usefullmprovements in Seat Attachments for Water-Closets, of which the following, taken in connection with'the accompanying drawings, is a specification.

My invention relates to seat attachments for Water closets and it consists in certain novel features of construction, arrangement and combination of parts which will be readily understood by reference to the description of the accompanying drawings and to the claims hereto appended and in which my invention is clearly pointed out. Figure 1 of the drawings is a central vertical section of so much of a'water closet as is necessary to illustrate my invention. Fig. 2 is a partial plan of same. Fig. 3 is a horizontal section on line 2, 2, on Fig. 1 looking upward, and Fig. 4, is a partial side elevation of the same. Fig. 5 is a sectional elevation of the hinge bearing stud and socket drawn to an enlarged scale. Fig. 6 is a'vei'tical section of the same on line 3, 3, on Fig. 5. Fig. 7 is a sectional plan the cutting plane being on line 4:, 4, on Fig. 6. Fig. 8 is a vertical section illustrating amodified construction of the hinge'stud and socket. Fig. 9 is a sec tional plan of said modified 'form f hinge" stud and socket, the cutting plane being on line 5, 5, on Fig. 8; and Fig. 10 is an inverted plan of both forms of hinge socket.

In the drawings A is the closet bowl having the annular fiushing pass'age a and the flush ing pipe spud b to which .the water supply pipe, not shown, maybe connected in any well known manner, and having formed integral therewithtwo ears c, c, on opposite sides ofthe spud 19 as shown, all formed of porcelain or earthenware.

In an opening in each of the ears 0, c is set a stud (1 provided with a collar 01 to rest upon the upper surface of the ear 0 and has fitted on its lower end the washer e of rubber or other elastic material, the metal washer f and the nut g5 The stud d extends upward from the collar d, terminates at its upper end in a conical or rounded bearing surface and is provided with a longitudinal slot extending from near the collar d nearly to its conical upper end which slot may extend through the stud d as shown in Figs. 5, 6 and 7 or only a short distance into said stud as shown in Figs. 8 and 9.

A hinge section B, provided with oppositely projecting studs orjournals -h and h, and a socketextending from its lower and upward nearly to its upper end, with a conical or concave bearing in the upper end of said socket, is mounted upon each of the studs d, so as to rest upon its conical or rounded upper end.

The sockets in said hinge sections B are made to fit the studs 01, at points near their lower ends but areenlarged above said points so as to permit said hinge sections to be tilted outof perpendicular positions when for any reason they are lifted from their bearing upon the conical points of the studs d. These sockets may be enlarged only in two opposite directions, so that a cross section of said sockets near their upper ends will be oblong as shown in Fig. 7, or the upper part of said .socket may be in theform of an inverted fru'stum of a cone, a cross section of said sockets being circular in all its parts as shown in Fig. 9. 7 I l S is the closed seat provided on its under side with the rubber'buttons'orcushions 2'2 to rest upon the rim of the bowl A in a well ,known manner and having set in its rear edge or otherwise secured thereto the hinge sections j, j, in the outer end of each of which when raised or lowered. C is the cover, also provided with rubber cushions, k, k, to rest "upon said seat in a Well known manner, and

having secured to its rear edge the hinge sections Zl fitted to hearings on the studs or journals h h of the hinge sections B, about which said cover moves when raised or lowered.

The hinge sections B are connected to the studs (1 (1, so as to prevent the seat S and cover 0 being lifted. entirely away from the closet bowl, by the pins mm which are set in the socketed hinge sections B B and pass through the longitudinal slots in the studs (1, d, as shown in Figs. 5, 6, and 7, or by the screw pins 72 set in said socketed hinge sec tions and projecting into the shallow slots or 5 is'formed an eye to receive one of the studs. or journals h, h, about whichsaidseat moves grooves in said studs as shown in Figs. 8 and 9.

In the case illustrated in Figs. 5, G and 7 the pins m are arranged with their axes parallel to the axes of the journals h, h, but when the modification illustrated in Figs. 8 and 9 is employed the screw pins n 'n are arranged with their axes in vertical planes at right angles to the axes of the journals h, h. By this construction of the hinge connection to the porcelain closet, provision is made for the possibility of a considerable obstruction being, accidentally or otherwise, placed upon the closet beneath the seat which if the seat were rigidly hinged to the porcelain closet would be very liable to break the closet. With this construction if an obstruction be placed beneath the seat at the rear of its center and upon both sides of the bowl and a person sits upon the seat the front of the seat will be depressed and its rear will be raised but as the hinge sections B B will readily move upward on the studs (1, (6, no damage will result. If the obstruction should be on one side only of the bowl, the hinge sections B B would be lifted unequally and therefore would be tilted out of their normal perpendicular positions which the expanded sockets formed therein would permit, and no damage would be done.

The upper ends of the studs d, d, may be made conical as shown in Fig. 8, or rounded as shown in Figs. 5 and O, the upper end of the socket formed in the hinge sections 13 being made to fit the upper ends of said studs, and the journals h or h on said hinge sections 13 may be arranged with their axes in the same vertical plane as the axes of the socketed hinge sections B as shown or in front or at the rear of said plane and may be formed integral with said hinge section or be made separate therefrom, or the sockets may be secured in fixed positions to the closet and the studs form part of the hinge sections without affecting the principles of my invention, and therefore I do not wish to be limited to the precise construction shown in the drawings so long as the seat is so hinged to the closet that the hinge may rise and fall and be tilted from a perpendicular position when an obstruction is placed beneath the seat.

The studs d d may be secured to the closet as shown in the drawings or they may be set in a plate or form parts of brackets which are secured to the earthenware closet by independent bolts or in any other well known manner without affecting the principles of my invention as the particular manner of securing said studs to the closet is not a part of my present invention.

Vhat I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In combination with an earthenware water-closet; a seat mounted upon said closet; and a hinge connection between said seat and closet made in three parts one of which is so cured in a fixed position to said closet, an-

other is secured to said seat and the third is fitted to and movable vertically upon the part secured to said closet, and pivotally connected to the part secured to said seat.
